Strange glass behaviour

[Chrmez]

Hi,

I'm working on a car scene and I'm getting really weird glass behaviour on the side of the car.

I can see through the glass perfectly on the front/back but the sides give me weird reflections. I've flipped the normals, checked Ray Epsilon, subdivided the surface etc. Nothing seems
to work except pulling down the Index to 1, but that just kills the glass all together so that's not an option. I'm getting the same thing on all my car models, which is also weird so it feels like
it must be a render setting somewhere.

I've uploaded the scene here:

Thank you!

Nevermind, it was the thickness that was the problem. It was just flat.
